yItis-cu'stornaryto apply to beverage containers, such as beer cans,suitable identifying markings, and these markings commonly take the formof numeralsand are, applied rto the bottoms of the cans. In itsl moredetailed nature, therefore, the

' invention seeks to provide a lnovel machine, continuously operatingand connected With suitable delivery and discharge means for feedingcans' l to andfrom the machine, and embodying 'means for applying themarkings to the cans while ythey f are being` continuously fedthroughthe machine.'A

f Another object of the invention is to provide a machine of thecharacter stated embodying means for ink-stamping the can ends by arolling contact. n f

Another object of the invention is to provide a novelink-stampingroller, adjustable to accu- ".rrately time the applicationof the marking, novel ink applying means, a novel turret structure rotatable'in a vertical plane.y to continuouslyl feed cans past theink-stamping roller, and adjustable devices for enabling the handling ofcans of different heights. -I

With theabove and other objects in view that will hereinafter appear,`vthe nature of the invention will be more rfully understood by followingthe detailed description, the appended claims,

and the several views illustrated in the accom-` panying drawings.

In the drawings:

Figure l is a left side elevation of my improved machine;

Fig. 2 is a part plan and part horizontal section, the plane ofthe'sectionalillustration being that which includes the devices;

Fig. 3 is a vertical cross section taken at theA position of theink-stamping devices;

Fig. 4 is a right. side elevation, parts being broken away;

Fig. 5 is a detailed perspective View illustrating a fragment of a canand the ink-stamping'rotor.

The machine includes a base 5 having mounting pads 6 for facilitatingattachment of the machine upon the floor or any other suitable support.Right and left frame standardsvrespectively designatedl l and 8 areremovably secured as at 9 upon the base and are joined at their rearends by a cross rod lll, at their front ends by a cross connecting angleH, and at their upper age i5, as shown in Fig. l

vdepositedone by one into the'receiving pockets axis of the ink-stampingportions by cross rods i2A disposed. in. parallel spacedrelation, asshown in Figures 2,3 and 4 of. .the drawings.

`Opposed feed-inv casting members `I3 are mounted as at'l upon the'cross rods I2 and serve -to vsupport feed-in trackage l5. to 'whichrcans to'bemarked are fed byvgravity, as shown l.

in Fig. `1 ofthe drawings. l v

In alined bearings Il and It Aprovided respectively inthe frame members'i and 8, a cross shaft l! is secured and serves as a support for arotory sleeve 28. which is rotatableabout said shaft.A

' `A canieeding turret 2| is provided and is se-l cured uponk androtatable with the sleeve'ZL'as shown in FigureZ of the drawings'. Theturret notched as at Z'Zgto provide eight 'can receiving pockets aboutthe periphery of the turret. See

is secured to the right hand as shown, in Fig. 2. The cans I6 fed.` into.the

machine on the track ofthe drawings,l are of the turret, Aand as theyare moved about inthe clockwise direction, as shown in Fig. l, they areperipherally retained by a track memberl 24 which is concentric with theturret and'is secured at its upper end as at 25 to the rearmost crossrod i2, and as at 26at itslower end to the cross rod is! includes spaced`ilange` portions peripherally Figs. 2, S'and'll. A beveled gear driverring`23 The cans kare received from theturret onto` an ofitaketrack-2,7, a suitable ejector plate 28 being disposed `above the track2l and extended into the turret between the flanges thereof, asindicated n dotted lines in Figs.' 2 and 4 of the drawings.

can gauging ring 29 which is secured as at`30 to For holding the cansagainst longitudinal dis-` placement on the turret, I provide astationary the frame standard, as shown in Figs. 2 and 4 oly thedrawings. It will also benoted by reference to Fig. 2 of the drawingsthat the lower end of the sleeve 2U is externally threaded as at 3| toadjustably receive the abutment disc 32. The disc 32 cooperates with thering 29 inpreventing longitudinal displacement of the cans from theturret pockets, and, by adjustment ofl this disc toward and from thering 29, the machine can be adapted for handling cansof differentheights. Thel adjustments ofthe `discs 32 can be secured by the jam nut33.

. The standard l includes a sleeve bearing portion 34 horizontallyalined with the 4axis of the transverse bearings I1, I8. A bearing 35,re-

- movably secured as at 36 upon the Standard 1,

cooperates with the bearing portion 34 in rotatably supporting a drivershaft 31 on which is fixed a beveled pinion 38. The pinion 38 mesheswith and imparts rotation to the driver ring 23 and the turret 2| towhich it is secured. See Figs. 1 and 2 of the drawings. The shaft 31 isdriven through suitable reduction gearing from a motor 39 supported uponthe base 5.

A marking sleeve 40 is carried by the shaft 31 and is equipped with agrooved disc enlargement y 4i in the groove of which is mounted a rubberstamping ring 42 on which are carried two diametrically oppositelydisposed ink-stamping or marking dies 43. See Fig. 5. The sleeveincludes a collar portion 44 and is split as at 45 and provided Wth aclamping screw 46 which enables adjustment of the sleeve about the axisof the shaft for the timing of the contacts of the dies 43 with thebottoms of the cans I6 being vmoved by the turret.

Each bearing portion 34 and 35 includes a vslotted guide extension 41,and in the slot o each guide extension is mounted a bearing block 48.The blocks 48 rotatably support a shaft 49 which carries an applicatorroll 50. vThe roll 50 is preferably formed of brass and it will beobserved by reference to Fig. l of the drawings that this roll ispositioned for contacting the ink-stamping ring 42. Each block 41 isengaged by an adjusting screw I, as shown in Fig. 2, and by manipulationof these screws the pressure Contact between the roll 50 and the ring 42can be varied to determine the blackness of the inking.

Apinion 52 is secured upon the shaft 49 and is driven by a similarpinion 53 secui'ed upon the driver shaft 31. j

An ink fountain or reservoir 54, in the form of a sight feed liquidfeeder, is secured as at 55 on `the bearing extensions 41 and includes adrip nozzle 56 from which ink is deposited, drop by drop, ontotherotating roll 50.` v In order: to properly spread and distribute theink applied to the roll 56,1 provide a wiper 51 which is supported as at58 upon the `frame 1 and contacts the periphery of the roll.

In opera-tion the cans fed downwardly into the machine as shown inFigure 1 of the drawings are continuously moved, in a part circularpath, past the ink-stamping station at which the ink-stamping devicesare located. As the exposed can ends pass the marking station they areengaged, in rolling contact, by the dies 43 carried by the ring 42.'I'he parts are so timed that the ring 42 will rotate once foreachpassage of two cans so that the dies, disposed diametrically oppositelyon the ring `will engage alternate can ends. By adjusting the abutmentplate 32 the machine can be made to accommodate cans of differentheights, and by adjusting the sleeve 40 about the axis of the shaft 31 aproper timing of the die and can bottom contacts can suitably be gauged.y

After being ink-stamped in the manner illustrated in Fig. 5 of thedrawings, the continuously moving cans are fed onto the trackways 21 andout of the machine.

It is of course to be understood that the details o structure andarrangement of vparts may be variously changed and modified without de`f parting from the spirit and scope of my invenftion.

What I claim is:

l. In a can marking machine, a rotatable turret having a plurality of`can receiving ,pockets for continuously moving cans with an end of eachcan exposed, an ink-stamping rotor continuously rotatable in a plane atright angles to the plane of rotation of the turret and having thereon aplurality of marking` dies individually engageable in rolling contactwith the exposed can ends, and means for retaining the cans againstlongitudinal displacement from the turret comprising a-iixed guide raildisposed at the side ofthe turret adjacent the rotor and a guide memberad. justable in the direction ofthe axis of 'the turret and dispo-sed atthe side of the turret remote n from said rotor.

2. In a can marking machine, a rotatable turret having a plurality ofcan receiving pockets for continuously moving cans with an end of eachcan exposed, an ink-stampingrotor continuously rotatable in a plane`atright angles to the plane of rotation of the turret andhaving thereona plurality of marking dies individually engageable in rolling contactwith the exposed can ends, and means for retaining the cans "againstlongitudinal displacement from the turret comprising a guide raildisposed at the side of the turret adjacent the rotor and an endabutment disk threadably adjustable along the axis of the turret andadapting the turret to the moving of cans of-different heights withoutnecessitating any movement of adjustmentof the rotor.
